Hello,
If it's the case of the percentage requirement for admission to Class 1 in schools like Sainik Schools or any other schools, then it is pretty minimum in usual terms. The main criteria for getting admitted into Class 1 is mostly age-related and not the academic percentage since it's at the initial point in their school life.
General Guidelines
Class 1 admissions are rarely specific to academic performance or percentage requirements. The most reliable course of action would be to visit the school's website or contact the admissions office.
